The inner bottom surface of the basin ears is provided with a flushing channel connected to the basin body, and two claws are provided. The bracket is a U-shaped structure, and both ends are connected to the basin ears through sliding bearings, and is horizontally arranged at the rear side of the basin body;

[0007] The folding system includes two driven gears and two driving gears. The two driven gears are fixed on the two basin ears and close to the inner wall of the bracket. The two driving gears are respectively arranged on the inner wall sides of the bracket, driven by a motor or manually, and the driving gears are meshed with the driven gears.

[0008] The lifting system includes two static slide rails, two movable slide rails, a lifting cylinder, a plurality of cylinder body connecting plates and a cylinder rod connecting plate. The two movable slide rails are vertically fixed on both sides of the rear side surface of the bracket. The two static slide rails are vertically fixed on the wall behind the bracket, and the two static slide rails are respectively slidably matched with the two movable slide rails. The two ends of the cylinder rod connecting plate are fixedly connected to the upper ends of the two static slide rails. The plurality of cylinder body connecting plates are vertically and evenly fixed on the rear side wall of the bracket between the two movable slide rails. The lifting cylinder is vertically arranged between the two static slide rails. The upper end of the telescopic rod of the lifting cylinder is fixedly connected to the cylinder rod connecting plate, and the cylinder body is fixedly connected to the cylinder body connecting plate. A cylinder pressure regulating handle is provided on the lifting cylinder.

[0009] The flushing system comprises a flexible downpipe, a flushing pipe, a water tank, a seat cushion, two flushing valves, a dynamic downpipe, a static downpipe and two flow limiting valves in the flushing pipes. The water tank is located above and behind the bracket and is fixedly connected to the two moving slide rails. A water inlet is provided on one side of the upper end of the water tank and a safety valve is provided on the other side. The two flushing valves are arranged in basin ears on both sides. The upper end of the flexible downpipe is connected to the sewage outlet of the basin body, and the lower end is connected to the upper end of the dynamic downpipe. The lower end of the dynamic downpipe is inserted into the static downpipe. The bottom of the water tank is respectively connected to the inside of the flushing valves on both sides through the flushing pipes. The two flow limiting valves in the flushing pipes are circular sheet valve structures, which are respectively arranged in the flushing pipes below the water tank, and the two flow limiting valves in the flushing pipes are connected by a connecting rod. The seat cushion is located above the basin body, and the rear end of the seat cushion is fixedly connected to the middle of the connecting rod between the two flow limiting valves in the flushing pipes.

[0010] The flush valve comprises a flush valve moving valve plate, a flush valve static valve plate, a flush valve body and a valve cover. The flush valve moving valve plate is provided with two toggle holes. The flush valve moving valve plate is placed in a basin ear, and two toggle claws are inserted into the two toggle holes. The flush valve static valve plate is coaxially arranged on the outer side of the flush valve moving valve plate and is fixed to the flush valve housing. A plurality of arc holes are provided on the flush valve moving valve plate and the flush valve static valve plate. The flush valve body is buckled at the end of the basin ear, and the flush valve cover covers the end of the flush valve body.

[0011] Furthermore, the dynamic downcomer pipe and the static downcomer pipe are slidably connected and a sealing ring is provided at the connection.

[0012] Furthermore, the movable valve plate of the flush valve rotates synchronously with the basin body through the drive of the pusher claw, and the static valve plate of the flush valve is stationary. When the basin body is at the 90° position, the arc-shaped holes on the movable valve plate of the flush valve and the static valve plate of the flush valve are completely staggered, and the flush valve is closed. When the basin body moves from the 90° position to the 45° position, the overlapping portion of the arc-shaped holes on the movable valve plate of the flush valve and the static valve plate of the flush valve is small but gradually increases, and the flush valve gradually opens. When the basin body is at the 45° position, the movable valve plate of the flush valve and the arc-shaped holes on the static valve plate of the flush valve are completely overlapped, and the flush valve is completely opened. When the basin body moves from the 45° position to the 0° position, the overlapping portion of the arc-shaped holes on the movable valve plate of the flush valve and the static valve plate of the flush valve is large but gradually decreases until they are completely staggered, and the valve is closed.

[0013] Furthermore, the flow limiting valve in the flush pipe rotates synchronously with the seat cushion. When the seat cushion is folded and not in use at 90°, the valve plate of the flow limiting valve in the flush pipe forms an angle of 45° with the inner wall of the flush pipe, and the water discharge flow is small. When the seat cushion moves to 45° with the basin body, the valve plate of the flow limiting valve in the flush pipe is parallel to the inner wall of the flush pipe, and the water discharge flow is maximum.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The toilet system of the present invention can move up and down along the slide rail to achieve a certain range of height adjustment, so that the toilet user is in the best slightly squatting posture for defecation, which is particularly suitable for people of different heights, especially children and adults using the same toilet;

[0016] 2. The toilet bowl of the present invention can be folded up by 0-90 degrees, and the length is greatly reduced after folding. Combined with the wall-mounted design, it can effectively reduce space occupation, better save the limited space of the bathroom, and facilitate hygiene.

[0017] 3. The closed design of the water tank of the present invention can store the water pressure of the tap water network system. The water tank opening design is to open the dynamic and static valve plate to flush the toilet. The flush valve can be opened and closed when the toilet bowl body is folded between 0° and 45° and 90°. The flushing volume can be controlled by the folding speed to achieve high-pressure water 45° position fast direct flushing. A flow limiting valve designed in the flushing pipe is also arranged in the water outlet pipe of the water tank, which is connected to the seat cushion. The flushing can be distinguished by urination or defecation by folding or putting down the seat cushion, which further realizes water saving. The water tank is designed with a safety valve to effectively control the water tank pressure within a safe range;

[0018] 4. The drainage design of the basin body of the present invention is a direct drainage with a flexible connection to the downpipe, which realizes the drainage function and the folding function at the same time. The flexible direct drainage design of the elastic hose reduces the drainage resistance and blockage, and is convenient for later maintenance, replacement, and pipeline dredging, solving the shortcomings of the existing toilet drainage bends in the market that are easy to be blocked and difficult to dredge after being blocked;

[0019] 5. The basin body of the present invention is designed with an action gear set, which can be equipped with a motor and a control system to achieve automatic 0-90° movement of the basin body, and to achieve self-cleaning and other actions and flushing volume by adjusting the speed of the basin body movement.

The water tank 8 is located above and behind the bracket 2 and is fixedly connected to the two moving slide rails 5. A water inlet 6 is provided on one side of the upper end of the water tank 8 and a safety valve 7 is provided on the other side. The two flushing valves 12 are arranged in basin ears 23 on both sides. The upper end of the flexible downpipe 1 is connected to the sewage outlet 24 of the basin body 10, and the lower end is connected to the upper end of the dynamic downpipe 13. The lower end of the dynamic downpipe 13 is inserted into the static downpipe 14 for sliding connection and a sealing ring is provided at the connection. The bottom of the water tank 8 is respectively connected to the inside of the flushing valves 12 on both sides through the flushing pipe 3. When the basin body 10 moves from the 90° position to the 45° position, the flushing valve 12 is fully opened to achieve high-pressure water 45° The flushing valve 12 is completely closed when the basin body 10 moves from the 45° position to the 0° position. The two flow-limiting valves 15 in the flushing pipes are circular sheet valve structures, which are respectively arranged in the flushing pipes 3 below the water tank 8, and the two flow-limiting valves 15 in the flushing pipes are connected by a connecting rod. The seat cushion 9 is located above the basin body 10, and the rear end of the seat cushion 9 is fixedly connected to the middle of the connecting rod between the two flow-limiting valves 15 in the flushing pipes; the flow-limiting valves 15 in the flushing pipes rotate synchronously with the seat cushion 9. When the seat cushion 9 is folded and not used at 90°, the valve plate of the flow-limiting valve 15 in the flushing pipe forms an angle of 45° with the inner wall of the pipe of the flushing pipe 3, and the water discharge flow is small. When the seat cushion 9 moves to 45° with the basin body, the valve plate of the flow-limiting valve 15 in the flushing pipe is parallel to the inner wall of the pipe of the flushing pipe 3, and the water discharge flow is maximum, which distinguishes between flushing for defecation and urination, and further realizes water saving.

[0038] The flush valve 12 comprises a flush valve moving valve disc 17, a flush valve static valve disc 18, a flush valve body and a valve cover. The flush valve moving valve disc 17 is provided with two toggle holes. The flush valve moving valve disc 17 is placed in the basin ear 23, and two toggle claws 25 are inserted into the two toggle holes. The flush valve static valve disc 18 is coaxially arranged on the outer side of the flush valve moving valve disc 17. A plurality of arc holes are formed on the flush valve moving valve disc 17 and the flush valve static valve disc 18. The flush valve body is buckled at the end of the basin ear 23, and the flush valve cover covers the end of the flush valve body. The flush valve moving valve disc 17 rotates synchronously with the basin body 10 driven by the toggle claws 25. The flush valve static valve disc 18 is fixed to the housing of the flush valve 12. When the basin body 10 is at a 90° position, the arc holes on the flush valve moving valve disc 17 and the flush valve static valve disc 18 are completely staggered, and the flush valve 12 Close, when the basin body 10 moves from 90° to 45°, the overlapping part of the arc-shaped holes on the flush valve moving valve plate 17 and the flush valve static valve plate 18 is small but gradually increases, and the flush valve 12 gradually opens. When the basin body 10 is at 45°, the arc-shaped holes on the flush valve moving valve plate 17 and the flush valve static valve plate 18 completely overlap, and the flush valve 12 is completely opened. When the basin body 10 moves from 45° to 0°, the overlapping part of the arc-shaped holes on the flush valve moving valve plate 17 and the flush valve static valve plate 18 is large but gradually decreases; the water tank opening is designed to be a sliding valve to open the toilet, and the flush valve can be opened and closed when the toilet basin body is folded between 0°~45°~90°, and the flushing amount can be controlled by the speed of the folding action. The flushing can be distinguished by the folding or lowering of the seat cushion 9 to distinguish between urination and defecation. The water tank is designed with a safety valve to effectively control the water tank pressure within a safe range.

[0039] Working process of the present invention:

[0040] The basin body 10 of the present invention can be folded and stowed at 0 to 90 degrees, which is much shorter than the existing toilet. At the same time, the wall-mounted design can effectively reduce the occupied space, better save the limited space of the bathroom and daily hygiene care, and protect this foldable wall-mounted, liftable, and pressure-storage flushing toilet method.

[0041] When the toilet is not in use, the basin body 10 is folded and stored at a 90° position. At this time, the seat cushion 9 is also at a 90° position. The flow limiting valve 15 in the flush pipe is perpendicular to the inner wall of the flush pipe 3. At this time, the vertical flushing volume when the basin body is put down for toilet use is the least. The arc holes on the flush valve moving valve plate 17 and the flush valve static valve plate 18 are completely staggered, and the flush valve is closed. At this time, the flushing system is disconnected;

[0042] When the motor quickly drives the driving gear 19 to drive the driven gear 11 or quickly manually drives the basin body 10 to rotate from the 90° to 45° position, the basin ear 23 rotates to drive the flush valve movable valve plate 17 to rotate through the pusher claw 25. The overlapped part of the arc hole on the flush valve movable valve plate 17 and the flush valve static valve plate 18 is small but gradually increases. At this time, the flushing system acts to wet the basin body 10, so that the basin body 10 is better flushed when sewage is discharged, and the water consumption is small.

[0043] When the basin body 10 is rotated from 0° to 45° by a motor or manually at a slow speed, the arc-shaped holes on the moving valve plate 17 of the flush valve and the static valve plate 18 of the flush valve completely overlap, the flush valve 12 is fully opened, the valve plate of the flow limiting valve 15 in the flush pipe is parallel to the inner wall of the flush pipe 3, and the water discharge flow is the largest. At this time, the flushing volume of the flushing system is the largest, the basin body 10, the sewage outlet 24 and the center line of the flexible sewer pipe 1 are in a straight line with small resistance, and the pressurized water flows from the water tank 8 along the flush pipe 3 into the flush valve 12, passes through the arc-shaped holes on the moving valve plate 17 of the flush valve and the static valve plate 18 of the flush valve, and flushes and discharges the dirt in the basin body 10 through the flushing hole, and the discharged dirt enters the moving sewer pipe 13 from the sewage outlet 24, and then is discharged along the static sewer pipe 14. A sealing ring is provided at the connection between the moving sewer pipe 13 and the static sewer pipe 14, which can effectively prevent leakage and sewer odor problems during sewage discharge;

[0044] During the rotation of the basin body 10 and the seat cushion 9 from the 45° position to the 0° position, the overlapped portion of the arc-shaped holes on the movable valve plate 17 of the flush valve and the static valve plate 18 of the flush valve is large but gradually decreases to be completely offset, the flush valve is closed, and the flush system is disconnected at this time.

[0045] Flushing when the basin body 10 is folded at 45° is more conducive to flushing away dirt, and the flushing volume can be manually controlled according to the dirt flushing situation. The speed of folding the basin body 10 is adjusted to achieve the purpose of saving water. The water-saving method of flushing the toilet with the toilet basin body at 45° is protected, and the flushing form with a pressurized water tank is protected. The flow limiting valve 15 in the flushing pipe can adjust the angle through the up and down movement of the seat cushion 9 to control the water volume, which can be used to distinguish between flushing for urination and defecation, and further save water.

[0046] When the toilet is in use, the basin body 10 and the seat cushion 9 are rotated to the 0° position, and the telescopic rod of the lifting cylinder 16 can be controlled to rise and fall. Since the upper end of the telescopic rod is fixed, when the telescopic rod is extended, the barrel of the lifting cylinder 16 drives the bracket 2 to slide downward along the static slide rail 4 and the movable slide rail 5 through the cylinder body connecting plate 20, thereby reducing the height of the basin body 10, and at the same time, the movable drain pipe 13 extends downward into the static drain pipe 14. Conversely, when the telescopic rod is shortened, the height of the basin body 10 rises, and the movable drain pipe 13 extends upward accordingly. The above operation can realize the function of adjusting the height of the toilet according to the height of the user, and the cylinder pressure regulating handle 22 can be used to adjust the air pressure inside the cylinder to adjust the up and down movement of the cylinder.
